2.Antimicrobial Resistance of Helicobacter pylori Isolates in Korea.
The Korean Journal of Helicobacter and Upper Gastrointestinal Research 2018;18(2):82-88
Antimicrobial resistance is a growing problem in the eradication of Helicobacter pylori. A combination therapy with proton pump inhibitor, clarithromycin, and amoxicillin is recommended as the first-line treatment regimen in Korea. However, the eradication rate with a standard triple therapy has been unsatisfactory in the last decade, and one of the main reasons for treatment failure is the increasing prevalence of strains resistant to antimicrobials. Therefore, comprehensive and detailed information on antimicrobial resistance is mandatory to optimize the strategy of eradication treatment. The antimicrobial resistance of H. pylori is reported to vary according to study population, geographical region, and test methods. In this review, the prevalence of antimicrobial resistance of H. pylori isolates in Korea is summarized on the basis of recent studies.

An association of low total cholesterol in blood with psychiatric diseases and suicidal behavior has been suggested. As part of an attempt to further explore this relationship, we examine first, whether serum cholesterol levels in psychiatric patients with suicidal attempt would be lower than in non-suicidal psychiatric inpatients or normal controls, second, whether such significant difference of cholesterol levels would be present when the diagnostic groups are analyzed separately, third whether low cholesterol level would be associated with a history of serious suicidal attempts, and finally, whether low cholesterol level in suicide attempters is as state or a trait marker. We determined the serum cholesterol levels in 231 patients admitted to an emergency room following an suicidal attempt, in the same numbers of age-, sex- and diagnosis-matched non-suicidal psychiatric controls, and in the same numbers of age-, sex matched normal controls. The seriousness of an attempt was divided into 5 grades according to the degree of the resulting medical injury. Total cholesterol levels in suicide attempters were significantly lower compared with both psychiatric and normal controls, when sex, age, and nutritional status(i.e., body mass index) were controlled for. This significant relationship was observed in major depressive disorders and personality disorders, but not in schizophrenia and bipolar type I disorders. The severity of suicide by a lowering of blood cholesterol was related to the magnitude of the cholesterol reduction. After treatment of their psychiatric ailments, the cholesterol levels in suicide attempters were significantly increased. This result suggests that low cholesterol level in psychiatric patients might be a potential biological marker of suicide risk. It is hypothesized that low cholesterol levels is associated with the suicide by modifying the serotonin metabolism, the production of interleukin-2 and melatonin metabolism in psychiatric patients.

5.Inhibitory effects of 2,6-di-tert-butyl-4-hydroxymethylphenol on asthmatic responses to ovalbumin challenge in conscious guinea pigs.
The Korean Journal of Physiology and Pharmacology 2018;22(1):81-89
This study evaluated the anti-asthmatic activities of 2,6-di-tert-butyl-4-hydroxymethylphenol (DBHP) that is a potent phenolic antioxidant in edible vegetable oil. The effects of DBHP on bronchial asthma were evaluated by determining the specific airway resistance (sRaw) and tidal volume (TV) during the immediate asthmatic response (IAR) and the late-phase asthmatic response (LAR) in guinea pigs with aerosolized ovalbumin-induced asthma. Recruitment of leukocytes and the levels of biochemical inflammatory mediators were determined in the bronchoalveolar lavage fluids (BALFs), and histopathological surveys performed in lung tissues. DBHP significantly inhibited the increased sRaw and improved the decreased TV on IAR and LAR, and also inhibited recruitment of eosinophils and neutrophils into the lung, and release of biochemical inflammatory mediators such as histamine and phospholipase A₂ from these infiltrated leukocytes, and improved pathological changes. However, anti-asthmatic activities of DBHP at oral doses of 12.5 to 50 mg/kg was less than those of dexamethasone (5 mg/kg, p.o.) and cromoglycate (10 mg/kg, p.o.), but more potent or similar to that of salbutamol (5 mg/kg, p.o.). These results in the present study suggest that anti-asthmatic effects of DBHP in the guinea pigs model of OVA-induced asthmatic responses principally are mediated by inhibiting the recruitments of the leukocytes and the release of biochemical inflammatory mediators from these infiltrated leukocytes.

BACKGROUND/AIMS: The purpose of this study was to determine the clinical parameters for a differential diagnosis between a malignant and benign stricture of the ampulla of Vater with a grossly normal appearance and to evaluate the diagnostic accuracy of the use of an endoscopic biopsy for the prognosis of ampulla of Vater cancers. METHODS: Medical records and cholangiograms were retrospectively reviewed. In order to determine the clinical parameters useful for a differential diagnosis, clinical manifestations, laboratory findings and the common bile duct diameter were compared between malignant and benign strictures. The diagnostic accuracy of the use of an endoscopic biopsy and the clinical features of patients with an ampulla of Vater cancer were analyzed. The survival rate after management was also evaluated. RESULTS: Nine patients with a benign stricture and 15 patients with a malignant stricture were included in this study. The levels of serum bilirubin, alkaline phosphatase and alanine aminotransferase were significantly higher in patients with a malignant stricture than in patients with a benign stricture (p<0.05). Of the patients who underwent surgical management, 93% had stage I or II disease. All of the patients were alive up to a mean follow-up period of 50 months. CONCLUSIONS: Liver function tests and the use of an endoscopic biopsy are useful in the differential diagnosis of a stricture of the ampulla of vater with a grossly normal appearance. Cancer patients typically present with an early stage and the prognosis is relatively good.

It is recognized that rebleeding of traumatic hyphema may predispose patients to several complications including decreased visual acuity. We reviewed the medical records of 92 patients(92 eyes) with the diagnosis of nonperforating traumatic hyphema. The relative efficiencies of Aminocaproic acid and systemic Predisolone for reducing rate of rebleeding and their side effects were evaluated under the statistical analysis. Fourty-seven patients received an oral dosage of 50 mg/kg of Aminocaproic acid every 4 hours for 5 days(up to a maximum 30 gm/day), and fourty-five patients took an oral dosage of 0.6 mg/kg of Prednisolone daily in two devided doses. The frequency of rebleeding was not statistically significantly different between the aminocaproic acid treated group(4.3%, 2/47 patients) and the prednisolone treated group(6.7%, 3/45 patients). The developing rates of their acute adverse reaction were statistically different between the aminocaproic acid treated group(44.7%, 21/47 patients) and the prednisolone treated group(20%, 9/45 patients).

PURPOSE: To report a case of acquired lacrimal fistula caused by silicone tube remnant. CASE SUMMARY: A 56-years-old female who suffered from purulent discharge in inner skin of the right lower eyelid visited our clinic. Lacrimal fistula was found in the skin at the medial side of the right lower eyelid. The patient reported that she had a silicone tube intubation operation 3 years prior due to a nasolacrimal obstruction of right eye. On syringing test, saline solution and purulent discharge were drained from the fistula skin opening and there was no nasolacrimal obstruction. After admission, antibiotic treatment and potadine soaking dressing were performed to facilitate spontaneous closing of the lacrimal fistula. However, the lacrimal fistula relapsed and lacrimal fistulectomy and bicanalicular silicone tube intubation were performed. During surgery, silicone tube remnant material not totally extubated at the lacrimal sac was found which we removed. Postoperatively, systemic antibiotic therapy was administered and the chronic inflammation improved. CONCLUSIONS: We report a case of lacrimal fistula caused by silicone tube remnant in the lacrimal sac. Acquired lacrimal fistula caused by a silicone tube remnant can be treated by fistulectomy and silicone tube remnant removal.
